The deltaflow flometer is continiously developed and inprooved and we hold several patents on the deltaflow Technology. But we do not only rely on our own know-how %u2013 systec is furthermore co-operating with well known partners sich as the institute for flow mechanics of the University of Erlangen oder the PtB in Braunschweig.
Due to the special probe profile the deltaflow can assure a high level of precision and excellent process viability, even in extreme conditions causing the lowest residual pressure loss. The deltaflow has been installed several thousand times.
Typical Applications are flow measurement of steam, perssurized air, water, liquids, stack gas, flare gas, natural gas.
Typical industries where our deltaflow integrating pitot tubes are used are Power Plants, Chemistry, Petrochemistry, Gas- and Oil Exploration, waste water plants.
The program to size and design the deltaflow is very self-explanatory and you can download it for free from our web-page as a Windows file (Windows 9x, 2000 and NT).
You can find more details in the referring information sheets. At the bottom of this page you can find links to the information sheets and to the software |

EE66 Series
Air Velocity Transmitter for measurement down to "0" m/s
EE66 air velocity transmitter series are designed for high accuracy measurement of lowest air velocities. It is the ideal solution for laminar flow control and special ventilation applications. The E+E thin film sensor is operating on an innovative hot film anemometer principle. This guarantees excellent accuracy for air velocity down to almost 0 m/s, which is not possible for conventional anemometers with commercial temperature sensors or NTC bead thermistors
EE66 series are available with current or voltage output, the measuring range and the response time can be selected with jumpers by the user.
Measuring range: 0...1 m/s; 0...1.5m/s; 0...2m/s (adjustable by jumpers)
Response time: typ. 4s or typ. 0.2s (adjustable by jumpers)
Outputs: 0...10 V or 4...20 mA (adjustable by jumpers)
Supply: 24V AC/DC

Measure the mass of air ingested by a gasoline or diesel engine using hot wire anemometry. The concept is simple; the implementation is unique.
At the heart of the design of Delphi's Probe Air Meters is a platinum-based, glass-coated, heated sensing element. The element is a low mass, quick responding device used in a bridge circuit configuration. It is very robust to damage from dust impingement. Delphi's Probe Air Meters feature a patented dimpled flow management pattern that provides more consistent air flow across the sensing elements, enabling outstanding performance in application-specific ducting.
Delphi's family of Probe Air Meters includes:
· Probe Single for unidirectional air flow applications
· Probe Dual features two heated sensing elements
· Probe Bypass for 4- and 5-cylinder turbo engines
Delphi has delivered more that 40 million air meters since 1993. |

Mass Airflow sensors contain a thin-film, thermally isolated bridge structure containing heater and temperature sensing elements. The bridge structure provides a sensitive and fast response to the flow of air or other gas over the chip. State-of-the-art chip design and manufacturing techniques allow the microbridge to be remarkably sensitive, fast, small. Used wherever airflow needs to be measured.

Solid State Flow Sensors
Designed to monitor for positive presence of cooling airflow, this velocity sensor operates on 5V DC. The sensor can be mounted on a board, in a socket, or hard-wired to a bracket. The SAF is an AMBIENT COMPENSATED device affording close setting tolerances up to 60°C. This product is available hermetically sealed for use in hazardous or contaminated environments.
- SAF Series Air Flow Sensor
The advanced SAF Series Airflow Switch provides early detection and protection from overheating in mainframe computers and peripherals, large power supplies; HVAC applications, medical diagnostic equipment, and other complex electronic systems requiring forced air cooling.
- DLS Series Air Flow Sensor
The new thermal emulator, or "Thermulator," is a switching device that monitors both temperature and air velocity in a forced air cooling system. This dual output logic switch (DLS) has the unique capability of providing two separate, preset alarm logic outputs. |
